T allwliom it may concern: Be it known that I, Lewis yfulImprovements in Gas-Producers; and I do h'ereby declare the following to be a full, clean-fand exact description of the invention,

vsuch as will enable others skilled in the art to which it'appertainsto make and usesthe same, reference'being had to the accompany# ing .drawings, and to the letters and gures of reference marked thereon, which form a 'part 'of this specification.

This invention relates to new and useful improvements .in gas producers, the object nin `View being tov generallysimproveupon andrender more eliicient the under feed type of producers.

C. PARKER, a. .c'itize of the United States, residing at `Hami ton, in the county'of Butler and State of Ohio, have invented certain new and us`e- I illustrate my invention in theaceompanyy ai@ ieiaiis of the drawings by letter, A designates the shell .of the producerwhich is'of .the usual con- Patentpd Oct. 20, i908.

v Gr designates a bracket` arm which is fastened. to the feed pipe and affords means for supporting and reinforcing the f same. Mounted iivithin tlqie outer end of the feedv p1 e 1s a p unger havinfr a proj eetino` pin extending forward iiilo said pipe and upon the opposite side of the plunger is a bar I having rack teeth I- thereon adapted to mesh with the teeth J uponthe curved end of the lever K which is `pivotally mounted upon a pin K. i A coal hopper N leads into the feeding pipe 'adjacentto its outer end and` through which `fuel is admitted to the pipe. It will be noted that said'plunger is elongated so that, when it is pushed forward by means of said lever, itwill shut off the feeding of the coal` into the pipe until the plunger is withdrawn vpast the lower thecoal chute or hopper.

A pipe L havinga valve L2 therein, leads endof through the wall ofthe producer below `the grate and communicates with the interior of the fuel vfeeding chute, to allow steam and water to be introduced therein forA the purpose of preventing thecoalin the pipe from coking and adhering thereto.. Asecond pipe 4L leads through the wall of the producer l.

, and opens` into the space below the rates and through which air and steam may. e introduced. A` blower is mounted within the casing O and whichcommunicates with'said pipe L, a handle Q being connected to theblower .affording means whereby the same may be worked by hand power.` Depending from the outer marginal edge of the band or ring C isa shell R .which forms with the WallV of the producer shell a passageway through which ashes, as they fall off the 'edge of the I hand or ring C, pass into the ash receptacle beneath, acoess 'to `which is hady through thev The operation of the apparatus isi-as `fol-A ylows:-In` startingthe space between shell A and shellR 'is filled with ashes when a fuel free from tarry or volatile hydro-oaryhonsis used to feed the feed pipe. Fire is preferably started from dry wood or charcoal which 'is'placed` upon the grates and ignited. .The blower 'within the casing ()l is operated to force thecombustion and-coal' or coke delivered to the grate through the feed pipe, until the fuel col-umn has a depth of fifteen or `twenty inches of incandescent coal, Y

1l() feeding the same upv through the feed. pipe i after which soft coal maybe introduced by j by working the plunger back and forth. As V the volatile vapors .are gasified from the soft coal as it becomes heated, gradually the rich hydro-carbone are decomposed in passing up through the incandescent zone of coals above the grate and thus form a fixed producer gas. `After the rich tarry vaporsv apron and the surrounding Wall of the pro'- ducerl shell into theash chamber beneath.

It will be noted that, by the construction of a gasproduceras shown and described,

all ofthe air is caused to pass u through the mass of fuel and is uniform y distributed through the. incandescent coals, the ash as it is formed falling back down without effecting the combustion or gasification of the coal. By the arrangement of the grates which are on a line with the upper edge of the feeding pipe and also in a line with .the band or ring over which the ash falls, it will be noted that the grate may be, actuated to let thel ash and clinker down and' at the same time not produce any cracks or openings up through the fuel column, the air for com' bustion passing through the grate bars without any interference with the ash.

That I claim to be new is l l. A gas producer comprising a shell, an under feed fuel pipe with its upper end flaring 'and -passing through the wall 'of the shell, means for feeding the fuel therein,

grate-bars mounted within the shell and inv a line with the eXit end of said feed pipe, a band surrounding said grate bars and having a space intervening between the outer marginal edge thereof and the shell of the gas producer, and an apron depending from lgrate bars mounted within the gas producer and in a line With the exit end of the feed Ythe'. outermarginal edge ofA said band and i e 'a band 'surroundinfr said Grate bars ywith a space intervening between its outer, marginal edge and the surrounding wall of the gas producer shell, and an aprendepending from lthe band and forming with the wall of the shell an ash passageway, as

Yunder feed fuel pipe with its upper end flaring and passing through the wall of the shell, a plunger mounted within said pipe and having a pin projecting from the inner endl thereof and extending into said feed pipe, rack teeth upon the rstem of the plunger, a. pivotal lever having rack teeth in mesh with the teeth of said stem, rocking grate bars mounted on a level with the upper exit end of saidv feed pipe. an operating rod pivotally connected to said grate bars, an ash hand surrounding the grate bars and in the samev plane therewith, a space intervening between the marginal edge of said band and the surrounding wall'of the producer shell, an apron depending from said band, a pipe leading through said shell and having' an exit end beneath said bars, as set forth. y I
